I have noticed ever since i brought my AI i get some water in one of my amas . On the weekend i got over a couple of litres in a few hours . I have replaced the bungs and still get the same results in only 1 ama. So confused why one would leak and why my mates are so airtight when he undoes his bungs they air rushs into his amas . Is this a common issue or should i just contact my dealer to lodge a warranty?The bungs position on the amas makes it impossible to get all the water out of the amas, i use a hose and syphon it. thanks
